SUMMARY:Stéphanie ROCCIA (LPSC-CNRS/UGA\, Grenoble)
DESCRIPTION:The search for neutron electric dipole moment at PSI\nRésumé : \nThe Universe and its history are simultaneously very well understood and still a big mystery. We have amazing tools from satellites to\nobservatories to weight the universe over its history. But the components of the Universe can simply not yet be explained by physicists. To get the full picture\, we need to identify and understand the interactions at play throughout the life of the Universe. This is the meeting point between particle physics and cosmology. At this meeting point stands the neutron\, a common particle that we can uniquely use in high precision experiments.\nI will present how experiments searching for a permanent electric dipole moment of the neutron (nEDM) aim at discovering new sources of CP violation beyond the Standard Model of particle physics and understanding the origin of the matter-antimatter asymmetry of the Universe. The quest for the neutron electric dipole moment started more than sixty years ago. In recent experiments\, polarized ultra-cold neutrons are stored in material bottles.\nI will present the ongoing efforts at the Paul Scherrer Institute in Switzerland where the n2EDM spectrometer has taken the first “physics data” in 2025. A large fraction of this dataset is dedicated to measurements of the UCN spectrum. I will present the newest UCN spectroscopy techniques that were recently published and the reasons for the importance of a deep understanding of the UCN spectrum. \n— \nHanno Filter (College 3 Secretary) \nExternal visitors may ask for a site access to tellier(at)ill.fr \nZoom link : https://ill.zoom.us/j/98964195699?pwd=vPhNT17CAeoDUr7QX4PjfyPnWsHuMU.1 – Password : SeminarC3
